For those who might be under the impression that rejiggering the placement of storylines was unique to Voyager, I will point out that once Paramount decided to punch up Deep Space Nine's rating by adding the Klingons and/or Worf in its fourth season, there was a whole story displaced by about half a season that was supposed to end the third season. In fact, the show's producers often struggled to make the Klingons relevant, and even struggled with what to do with the Dominion after the strong push in the third season. It wasn't until the sixth season that things really fell into place. But fans always think more kindly of Deep Space Nine. Well, those who like it. It bears reminding that there are just as many fans out there who hate Deep Space Nine as Voyager or Enterprise. It's just, those who love it love it quite passionately. Cult within a cult and all.
I never got why Voyager got so much hate. I always chalk it up to burnout. At the point it debuted, fans had had new episodes of Star Trek for nearly a decade, and it was the third series from the same general period. There were a lot of vacuous complaints that it had no idea what to do with its premise, but those first two seasons are jam-packed with premise-heavy episodes, and the fans hated them, too (the Kazon were "too much like the Klingons," and looked "stupid;" never mind that the Klingons would look stupid to you, too, if you were in the right mood). The third season was a reset to try and find a more comfortable groove, and then of course the Borg happened, and the producers thought they had found something the fans would really love. But the fans decided they had already had enough of the Borg...It was a time of being incapable of pleasing the fans, because the fans had had enough. Paramount wanted to keep the franchise going, but the fans didn't. They were satisfied with their happy memories of Kirk, of Picard (who the fans also hated, originally, and only came around to three seasons in, and eventually rejected all over again pretty much for each of his movies, except First Contact, which plenty of fans still dismiss as an Alien rip-off and "not true to the source material").
But...yeah, I'm pretty passionate about this sort of thing. I don't need everyone to like all of Star Trek. But I don't need them regurgitating opinions they formed for reasons they still can't admit, either.
